Fig. Fig. 1 Teves Mk iv Proportioning valves

The in-line proportioner valves to the rear brakes may be removed by disconnecting the brake lines from each end of the valve. Clean the fitting thoroughly before disconnecting them. Always use 2 wrenches to turn brake fittings and be prepared to collect fluid spillage in a clean container. Plug both brake lines immediately to prevent the entry of dirt. During reassembly, tighten the line fittings to 11 ft. lbs. (15 Nm).
